WebCrypto X25519 wrong algorithm test does not work properly

[Frosne]

The test "X25519 mismatched algorithms" is supposed to check that the curve in the publicKey corresponds to the curve in the algorithm. See: X25519 mismatched test

But it looks to me that none of the browsers pass the check not because of the implementation issue, but rather because the X448 is not supported. As I am not sure that it's gonna be supported in the near future, should we rework the test?
